Application filed January 25, 1911. Serial No. 604,667.

To au whom t may concern Be it known that I, WILLIAM W. BRIGHT, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Concrete' insert; and l do hereby declare the Yfollowing` to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same, reference beingl had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of the specification.

My invention relates particularly to devices for holding or supportingr shaft haugers. brackets, or other articles from the Walls, floors or ceilings of concretestructures. but is not restricted to such use as it may be used in any connection for which it may be adapt-ed or appropriate.

The object of my invention is the provision, in combination with a beam or other form of article adapted to be anchored in concrete, of a bolt or similar articleseeur ing means which is lreld for lateralv adjustment relative thereto to facilitate an alining of a plurality of such bolts with the article or articles to be hung' or attached to the concrete should the beam or other holding' means be out. of true with the de sired line of such article.

The invention is fully described in the following specification, and "while, in its broader aspect it is capable of embodiment in numerous forms, a preferred embodiment thereof is. illustrated in the aecon'ipanyinefl drawings, in Which,-

Figure 1 is a side elevation of an insert embodying mv invention embedded in concrete and With a part broken away. Fig. .2 is a view of the open side of the insert with bolts projecting therefrom.. Fig. 3 is an enlarged cross-section of theinsertand Fig. l is an enlarged viewof the bolt.

Referring to the drawings, l designatesl the insert or anchor of my invention, which is intended to be embodied in a concrete Wall, Hoor or ceiling with its outer side substantially liush With the face thereof, and forI the purpose of securely anchoring the insert within the 4concrete it is preferably provided on its inner side with anchor means 2 of any suitable form.

The inserts l., Which are preferably of beam form and of suitable length to accommodate one Or more of the article holding bolts hereinafter referred to, are hollow throughout substantially the entire lengths thereof and provided on their outer sides with a longitudinally extending slot or opening' 3 to the interior thereof.

The slot or opening 3 is of less width than the hollow il of the insert and has its side walls each step ed to provide shouldered longitudinal langes 5 for receiving the outward thrust of the head or nuty (S of a bolt, the shank -7 ofwhich is intended to project outwardly through the openingl 3. The bolt head Or nut 6 isV of suitable Width to rest on and be supported by the flanges 5 and to engage between the shoulders of said flanges to prevent its turning. The hollow 4 of the insert, however. is of suitable ividth-to permit a free turning' of the bolt head or nut 6 therein when moved into register therewith, as Shown by dotted lines in Fig. 8. The Opening 3 is cut away at either or both ends of the insert, as shown at 8, or at any. other desired point therein to permit an insertion or removal of a nut or holt head 6 therethrough as is apparent. YVhen a bolt is engaged with the insert it'may be placed at am7 desired position therein by movingitlongitudinally in the space between the shoulders of flanges 5 or Within the hollow Il.

lt freuuentlv occurs in the construction of.' concrete buildings that the inserts to 'which shaft. hangers or other articles are to be an y ehorod become out of alinement with cach other or with the line of securing of the articles prior to or during! the setting of the concrete. To compensate for such feature the opening 3 of the insert is made of .greater Width than the shank of a bolt which is intended tO he anchored thereto and the shank of the holt is Offset from the center of the head or nut 6 thereof which is disposed Within the insert, as indicated. This enables the bolt shank to be placed in atleast four different positions transversely of the insert by a turning of the bolt head or nut G therein` as indicated in Fig. 2. To he more specific` the point of attachment of the bolt shank to the head or nut 6 is adjacent to one side thereof and preferahlv slightly nearer to one end of such side than to -the other so that the shankof the bolt may be placed adjacent to one side or the other of the insert opening' 3, or adjacent to but at one side or the other Of the center line of me. und

the opening by giving the bolt a one-quarter t-nrn in one direction or the other from such position. This feature is found to be of very great importance in inserts of the class described, and is not restricted to use in connect-ion with the particular type of insert shown. ln practice the lateral play of the bolt head or unit 6 within the opening 3 is vsucient to enable its shank to be placed in L l claim as new and desire to secure by Letters Patent, is,-- y I l. In combination, with a square head and an eccentric shank projecting outwardly therefrom, a hollow insert the interior of i which is of a width greater than the diameter of the head, saidinsert having an outer longitudinal opening of greater width than the diameter of the shank, the side walls of the opening being stepped to provide a pair of spaced longitudinal shouldered iianges, the head resting on the flanges and the shoulders engaging two of the sides of the head to prevent rotation thereof, the shank of the head extending through the opening, the interior of the insert above the shoulders being of suiiicient width toreceive the head and allow turning thereof when the head is raised above said shoulders to permit the shank to occupy various positions in a plane transverse to the length of the longitudinal opening, the longitudinal opening being of sutiicient Width to permit movement of said shank to its different positions.

.in combination with a hollow Insert formed with an outer opening the side walls of which lat-ter have a pair of shouldered flanges formed thereon, a member having an eccentric article engaging element extending outwardly therefrom, said member seatj width to permit movement of said eccentric element to its different positions.

3. In combination, with a memberhaving eccentric supporting means projecting outwardly therefrom, an insert, means .carried by the insert to support said member 'against outward movement, and means carried by the insert to engage said member to prevent rotation thereof, said insert having its interior of a width to receive the member to permit turning of the latter when the member is moved out of engagement with the means which prevent rotation thereofif to allow the eccentric supporting means of the' member to be adjusted to occupy various positions in a plane, transverse to "the, length of the inseit and to be againmoved into engagement with the means which hold same against rotation, said insert having an opening of suiicient width to permit movement of said eccentric supporting means to its different positions.v

In witness whereof, I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
